32-bit Microcontrollers with 48MHz Arm® Cortex®-M23 and Integration of 24-bit Sigma-Delta ADC
Jump to Page Section:
Overview
Description
The RA2A1 Group of microcontrollers (MCUs) uses a high-performance Arm® Cortex®-M23 core and offers highly integrated, high-accuracy analog capabilities. This group of ICs offers a complete MCU with analog solution for signal conditioning and measurement. The RA2A1 Group supports a wide operating voltage range of 1.6V to 5.5V. It includes a 16-bit SAR ADC, 24-bit Sigma-Delta ADC, comparators, operational amplifiers, and DACs. The RA2A1 MCU targets cost sensitive and low power industrial sensor applications where high resolution analog will become a cost benefit.
Features
- 48MHz Arm® Cortex®-M23
- 256kB Flash memory and 32kB SRAM
- 8kB Data Flash to store data as in EEPROM
- Scalable from 32-pin to 64-pin packages
- Capacitive touch sensing unit
- 16-bit SAR A/D, 24-bit SD A/D
- 12-bit D/A, 8-bit D/A
- OPAMP (3ch), ACMP-HS/LP
- USB 2.0 Full Speed
- CAN 2.0
- SCI (UART, Simple SPI, Simple I2C)
Applications
Applications
- Industrial automation (photoelectric sensor, fiber sensor, temperature sensor)
- Process automation (pressure sensor, flow control meter, single phase meter)
